Gene of the Week: Shyness
Research suggests that the degree of loneliness that any two people feel in a particular situation may vary widely, partly because of genetics. In fact, loneliness is half inherited, half environmental, says John Cacioppo, director of the University of Chicago's Center for Cognitive and Social Neuroscience....
Using data from more than 8,000 people in twin studies and sibling studies, in collaboration with the Netherlands Twin Register, Cacioppo and colleagues found strong evidence that genetics accounts for about half of the differences in loneliness among people in the study.
